SILL CONSTRUCTION.

To @ZZ y11i/tom it may concern:

Be it known that l, FREDERICK N. MAR- vIcK, a citizen of the United States, and a resident of Pine Bluff, in the county of Jeti'erson and State of Arkansas, have invented certain new and useful Improvements in Sill Constructions, of which the following is a speciiication.

My invention is an improvement in sill constructions, and has for its object to provide a construction of the character speciied wherein the heavywooden sill generally used is replaced by a plurality of pieces of relatively small cross section, thus permitting heart pieces to be used. c

In the drawings:

Figure 1 is a section on the line11 of Fig. 2;

Fig. 2 is a section on the line 2-2 of Fig. 1, both views looking in the direction of the arrows adjacent to the respective lines.

ln the embodiment of the invention shown in Figs. 1 and 2, the improved sill construction is shown in connection with a brick veneer wall. In this construction a foundation wall is provided, consisting of a base or horizontal portion 1 and a superstructure or vertical portion 2.

Suitable ventilators 3 may be provided in the superstructure, and upon the upper surface of the said superstructure is arranged a series of blocks 11, the said blocks being spared about sixteen inches from center to center, and the long dimension of each block is perpendicular to the plane of the foundation wall. The upper surface of the wall is preferably coated with asphalt or the like, the blocks et being arranged on this coating.

The sill 5 is composed of superposed Qx-ls, and these are held to the foundation wall by means or' bolts 6. These bolts 6 have their heads and approximately half of their bodies embedded in the concrete foundation wall, and the sill sections 5 have registering openings through which the bolts are passed, and the bolts are engaged by nuts above the sill section, Washers being arranged beneath the nuts as shown. Thus the sill is securely held to the foundation wall, and the inner or lining wall 7 of the ship-lap abuts against the outer faces ozt the sills, the lowermost plank of the said wall 7 resting upon the blocks 4. These blocks are of a length to extend from the inner face of the sill and Y Specification of Letters Patent.

the foundation wall to near the inner face of the brick veneer indicated, at 8, and it will be noticed Athat the wall 7 is spaced away from the veneer wall 8, the blocks 1 being of suiiicient length to extend from the inner lace oi the sill 5 beyond the outer face of the wall 7. Just above the blocks 4 is arranged a strip 9, the said strip extending the full length of the wall to catch and hold droppings of mortar from the wall 8 which might otherwise fall upon the foundation wall.

rThe floor which, in the present instance, is shown consisting or' a subfloor 10 and a linished floor 11, is laid upon joists 12 which, in turn, are laid upon the sills 5, the said joists being so laid that they will be at the blocks 4, as clearly shown in Fig. 2.

The studding 13 also rests upon the sills 5, the said studding being arranged alongside the joists 12 in the usual manner, and the lath and plaster wall 111 is separated from the wall 7 by the studding.

Means is also provided for making the walls vermin prooi", that is, for closing the space between the studding, the wall 7 and the wall 13. Strips 14 and 15 of two byfour material are arranged between each pair of adjacent j oists, the said strips being of a length to abut at their ends the joists, and they are arranged at right angles to each other as shown in Fig. 1, with abutting corners, to form a species of box between the joists, the strips and the wall 7. lVithin this box is arranged plastic material capable of hardening, as, Jfor instance, concrete, the said material being indicated at 16, and it will be obvious that the blocks 16 of concrete form a barrier against the passage of vermin, as, for instance, rats, mice and the like, from below the flooring to above the same.

As is known, large pieces of wood, that is, pieces having a relatively large cross section, decay faster than pieces having a relatively small cross section. It is also a fact that wood well ventilated will last longer than wood not so ventilated and that when the wood comes into contact with dampness it soon decays. The upper portion of the foundation wall in Fig. 1 constitutes a subsill, and this sub-sill is thoroughly ventilated from every side. The sill being composed of two pieces of relatively small cross section may be made from heart wood clear of sap,;and of a lasting wood, as, for instance, cypress or oak.V Perfect insulation against darnpness is provided, as is also Ventilation and protection' against vermin.
